Sadly for me it does not work.

Windows 10 x64, JDownloader2 64bit, Java 1.8.101 x64
7zip Binding version: 15.09-2.01beta
In the second when I try to extract a file (v5 or also older) the whole jdownloader process does not respond anymore and crashes.

Here is a log where I tried to extract an existing file on my machine with Extra/Extract:
09.10.16 14.17.53 <--> 09.10.16 14.18.04 jdlog://5511681887641/
